Quick Fractions for Busy Third and Fourth Graders
We've gathered all the fractions that 3rd and 4th graders need to know in one book!

According to a report published by the Korea Institute for Curriculum and Evaluation, the number of people who fail to learn fractions begins in the third grade of elementary school.
The reason why fractions are difficult is because they are unfamiliar with the two numbers, the numerator and the denominator.
How should I study fractions, which are so unfamiliar and difficult?

· Get ​​started with concepts through 26 curious questions!

The book begins with 26 curious questions.
These questions are taken from the concepts of fractions that 3rd and 4th graders must know.
In particular, questions that address confusing concepts, such as “Is 3/3 a proper fraction or an improper fraction?”, can help you determine whether you understand the concept accurately.
In this way, in the process of finding answers to questions, concepts are organized and principles are understood.
Additionally, the concepts and calculation principles are explained with pictures to increase understanding.
You can make the concept of fractions easier to understand by drawing a picture of sharing pizza or bread!

· Let's practice by gathering the fractions that we learned scattered throughout the 3rd and 4th grades!

Elementary fractions are taught from the first semester of the third grade to the second semester of the sixth grade.
Among these, ‘Comparing the meaning and size of fractions’ learned in the third grade and ‘Addition and subtraction of fractions with the same denominator’ learned in the fourth grade are the foundation of elementary fraction learning.
Build a solid foundation in elementary fractions with this book.
As the knowledge learned in the 3rd and 4th grades is combined, the system of fractions is established.

· Train with optimal operation problems to learn fraction concepts and finish with word problems!

Now that you understand the concept of fractions, it's time to practice them to become more comfortable with them.
However, if the number of problems is too large, you will become tired of studying, and if there are too few, you will not be able to solve them skillfully.
This book contains just the right amount of problems for busy third and fourth graders to maximize efficiency.
After completing the arithmetic training, you can solidify your basic concepts and develop your problem-solving skills through 'thinking and solving problems'.
Complete 3rd and 4th grade fractions quickly and easily with this book!

· Characteristics of the 'busy operation method'

1) Just 10 days to shape your math life! Customized learning available at home!
Even at home, you can accurately diagnose your child's current learning status and create a customized learning plan.
Choose one of the 10-day, 14-day, or 25-day progress charts based on the "My Study Plan" included in this book! For fourth graders, we recommend the 10-day progress chart to focus on completing calculations.
Just 10 days to address your learning deficits will be a crucial turning point that will determine your future math career.

2) Don't solve it unconditionally! Look at the concept and 'get the feeling~'
If you solve problems without properly understanding the concepts, you may hit a wall at some point.
Just as you need to consume a balanced diet to build basic physical strength, you need to learn concepts and principles during the training process to build a healthy foundation.
Unlike training books that only cover calculations, Busy Operation Method includes ‘friendly concepts’ for each lesson.
It is helpful for friends who are learning on their own, as it allows them to understand the principles and practice calculations through friendly concept explanations that can be understood just by looking at the title.

3) The teacher in the book! Solve the puzzle with the teacher using 'Busy Tips' and hints from Padok!
No more mechanical, haphazard solving! From useful problem-solving tips to error-reducing tricks, this guide offers easy-to-understand tips and hints throughout the book. Even if you're working on your own, you'll benefit from learning alongside a friendly teacher.

4) Scientific learning design! Baboo's "small steps" method builds skills!
No more mechanical, repetitive calculations! We've structured it so you can quickly learn the easy parts and practice more on the more challenging ones.
Additionally, the level of immersion has been further increased by designing the stages meticulously and scientifically using the 'small step' method of Busy, which gradually increases the level and challenges.
It doesn't suddenly become difficult, so anyone can immerse themselves in it until the end and build their skills.

5) Understand the language of daily life and make it your own, and you will gain confidence naturally!
It doesn't end with just practicing simple calculation problems.
You can develop mathematical thinking skills through 'thinking and solving problems' and prepare for descriptive problems that you will inevitably encounter in school through word problems.
This book is not just about calculations, but it is more than just a book about calculations, and it helps you develop the problem-solving and creative convergence skills required by the current curriculum!

· To those who guide this book!

1.
Please make sure to read the concepts and then solve the problems.
There are many children who work hard at solving math problems, but make mistakes even when the problem type changes slightly.
Because the concept is not solid.
Please make sure to read and understand the concepts.

2.
It's easier to understand if you explain it using familiar materials from everyday life.
This book explains the concept of fractions using real-life examples.
Even when eating pizza or castella at home, it's easier to understand if you talk about who ate what portion.
And when you finish studying, be sure to praise yourself!
